Meson 1.5.1 is available in the fd.o SDK and in Debian testing, so the
glib Meson policy says we can update. Update the minimum only as far as
1.4.0 because we don't yet have a need for 1.5.0.
This allows us to:
- Use file.full_path() to avoid deprecation warnings on str.format(file).
- Set c_std=gnu99,c99 to avoid deprecation warnings with gnu99 on MSVC.
Update all the CI builds to use the latest 1.4.x patch release, 1.4.2.
The FreeBSD runner cannot be updated via `gitlab-ci.yml`, so will be
broken for now.
Similarly, the macOS build will not work unless `-Dc_std=gnu99` is
specified at configure time, due to
https://github.com/mesonbuild/meson/issues/13639.
Alpine 3.19 ships with Meson 1.3.0, which has broken handling of File
objects and their paths. This causes (as far as I can tell)
un-work-around-able breakage of GLib’s build.
See https://github.com/mesonbuild/meson/issues/5273#issuecomment-1851811417
That should be fixed in Meson 1.4.0, but that might not be released for
a while. Because we’re here to test GLib, not Meson, let’s pin the Meson
version in the Alpine CI image to 1.2.3, which we know works and is
reasonably up to date (and is what the other CI images use).
